Physical characteristics
NGC 753 contains two main arms that extend to 180° on either side of the galaxy.{{Cite journal|last1=del Rio|first1=M.

This open structure of the arms may be due to the influence of NGC 759 which is a close companion of NGC 753 that lies {{convert|0.44|Mpc|Mly|abbr=on|lk=on|order=flip}} away.

NGC 753 has a supermassive black hole with an estimated mass of (2.2 ± 0.4) × 107 M☉.{{Cite journal|last1=Seigar|first1=Marc S.|last2=Kennefick|first2=Daniel|last3=Kennefick|first3=Julia|last4=Lacy|first4=Claud H.
